* Code was tested to be compiled with both gcc and aCC. However, if you
  plan to compile NetXMS agents and/or server on one machine and distribute
  binaries to another machines, we recommend to use HP aCC compiler if
  possible.

* Default HP-UX implementation of iconv() interface cannot handle UNICODE
  correctly, and if you doesn't have GNU libiconv installed or encountered
  any problems with agent connectivity, use --disable-iconv option of
  the "configure" script.

* Required patches for HP-UX 11.11
